Mathematics

Answer:

A 50% increase

Step-by-step explanation:

Area = length x breadth

Let illustrate this with an example

original dimensions

length = 4

breadth = 5

area = 4 x 5 = 20

new dimensions

length = 4/2 = 2

breadth = 5 x 3 = 15

area = 15 x 2 = 30

Percentage change = 30 - 20 / 20 x 100 = 50%

B) y = 3 = 2х<br><br> Is this relation linear or non-linear? Explain why.
Alika [10]

Answer:

I think you meant: y=3+2x, in that case, this is a linear answer

Step-by-step explanation:

Non- linear would look like this: K=2/3

Linear would look like this: Y=4x+7

Why:

It all comes to what is proportional and what is not.

marty made two types of cookies. he used 2/3 cup of sugar for one recipe and 1/4 cup of sugar for the other. how much sugar did
Bezzdna [24]
He used 11/12 of sugar.

(1) I multiplied the factors and denominators by eachothers denominators
(2) I ended up with the two converted fractions: 8/12 and 3/12. The reason for this step is because if the two fractions have the smae denominator, it helps make it easier to add the fraction.
(3) I added the fractions, getting the sum of 11/12

Good question!
